Mandibular Bony Exostoses or Hyperostosis: A Case Report.

Mandibular bony exostoses or hyperostoses are benign, non-neoplastic, localized bony outgrowths that are broad-based, slow-growing, and surface masses on the buccal or lingual surface of the mandible alveolar bone. Such exostoses grow over several years. Exostoses are more common in the maxilla posterior region along the maxillary tuberosity, called palatal exostoses. Torus palatinus occurs in the mid-line of the hard palate; mandibular torus or torus mandibularis occurs along the mandibular canine, premolar regions. We report a rare case of such bony exostoses on the lingual surface of the mandible in a 70-year-old edentulous male.
